An approach to assign individual marks from a team mark : the case of Australian grading system at universities

This study uses a new approach to assign individual marks from a team mark using individual contributions to a teamwork product. A team member’s contribution to a teamwork product, in the form of an individual weighting factor, is calculated using team members’ co‐assessment. A comparison of the proposed approach with existing methods has been discussed with the help of a typical teamwork example. The approach has been refined to make it applicable for the Australian grading system at universities. It has been implemented in a large undergraduate engineering course to observe its effectiveness in practice. The results show that the method encourages teamwork, penalises below‐average contributions and rewards above‐average contributions. An analysis of a students’ perception survey shows that students prefer the approach over alternative approaches.

The Iraqi Federation of Oil Unions : protests and public power in post-Saddam Iraq

Since the democratic elections held across Iraq in 2005 and 2010 much attention has understandably been paid to the new Iraqi government. Unfortunately, it has become increasingly clear that much of Iraq’s political elite are practising the type of governance referred to in the literature on other Arab states alternatively as ‘liberalised autocracy’ (Brumberg, 2002), ‘semi-authoritarianism’ (Ottaway, 2003) or ‘pluralised authoritarianism’ (Posusney & Angrist, 2005). That is to say, that the Iraqi government actually utilises (and controls) nominally democratic mechanisms such as elections, media freedoms, political opposition and civil society as part of their strategy to retain power. This is perhaps best demonstrated via the nine month political stalemate that followed the March 2010 elections and PM Maliki’s refusal to step down despite having narrowly lost the election. Not surprisingly, the Iraqi people have become increasingly disillusioned and critical of their political leaders – hence the mass protests that have swept across Iraq in the context of the popular Arab Revolutions of 2010-11.

However, these latest Iraqi protests are only the most recent and overt sign of the hidden geographies that are agitating towards democracy in this deeply troubled and increasingly authoritarian state. Since the invasion of 2003, a complex array of political, religious and ethno-sectarian factions have formed civil society movements; uncensored news has been consumed across the nation; ordinary citizens have taken to the streets to protest key government decisions; and various local councils have been formed, deliberating on key decisions facing their immediate communities (Davis, 2004, 2007). Given this context, this chapter focuses on the specific case of the Iraqi Federation of Oil Unions (IFOU), Iraq’s largest and most powerful independent workers union. The IFOU has repeatedly taken the Iraqi government to task over their poor pay and the dangerous nature of their work, as well as the government’s initial kowtowing to US plans to privatise the entire Iraqi oil sector. To do this, the IFOU have utilised a variety of very democratic mechanisms including peaceful strikes and protests, media campaigns and political lobbying. Such moves have met with mixed results in Baghdad – at times the central government has pandered to the requests of IFOU, but it has also gone as far as issuing arrest warrants for its senior members. The IFOU therefore serve as an interesting example of public power in Iraq and may well pose one of the greatest challenges to rising authoritarianism there.

E-governance as digital ecosystem : a new way to think about citizen engagement and the internet?

There has been a long history of attempting to deploy networked information and communications – mostly in the form of the Internet – to support the broad goals of effective, efficient and responsible democratic government. While there has been considerable talk about the way such technologies might promote better governance – through increased citizen participation in debates and discussions about future outcomes – there has been, in contrast, much action that actually uses the Internet for more efficient government, by creating online and networked interfaces by which citizens can transact business with government. There has been only limited success in using the Internet and similar communications channels to allow citizens to participate in their own governance. Undoubtedly, the Internet does facilitate public consultation. For example, the European Commission used an Interactive Policy Making web tool for public consultation on legislation for regulation of chemicals. Over 6,500 contributions were received over a period of 2 months and the consultation process led to the identification of key flaws in proposals, saving billions of Euros (Timmers,2008). However, consultation of this kind tends to be a mechanism for gathering opinion and gaining citizen approval for change that is not different except in transmission form than previous approaches based on meetings and written submissions. While the European Commission example can be seen as successful, Internet-based consultation can too easily become promotional or marketing oriented, as in recent efforts in Australian by the Federal Communications Minister to use a blog to discuss proposed changes to Internet censorship regulations: in this case, discussion and debate from participants appears largely to have been ignored in favour of a pre-existing position. This paper aims to provide a solution to some of these problems by drawing on the idea of how the Internet can host and support a digital eco-system.

Carbon dioxide corrosion inhibition : an overview of recent research on new inhibitor development

Since the introduction of inhibitors to the oil and gas industry in the 1940’s, corrosion inhibition has played a key role in carbon dioxide (CO2) corrosion control. Major inhibitor discoveries occurred from the late 1940's to the late 1960's, followed by the refinement of formulations and the development of improved application methods. Over the past two to three decades, although some new derivatives of existing inhibitors such as amide, amine and imidazoline have been reported, there have been few if any discoveries of new CO2 corrosion inhibitors. In recent years, the development of environmentally friendly inhibitors and the inhibition of localised corrosion have become driving forces behind new advances in corrosion inhibitor technology. Recently a rare earth metal organic compound, lanthanum 4-hydroxy cinnamate has been found to be an efficient corrosion inhibitor for mild steel in CO2 containing aqueous media. A resorcinarene acid has been found to provide effective localised corrosion inhibition by promoting a random distribution of insignificant anodic currents. The advent of advanced scanning probe techniques and an electrochemical integrated multi-electrode array have facilitated the discovery of corrosion inhibitors. This paper provides a brief overview of recent progress in this field.

Integrated depression management: a proposed trial of a new model of care in a low vision rehabilitation setting

Purpose:
Depression is a common problem among people with visual impairment and contributes to functional decline. This article presents a study protocol to evaluate a new model of care for those patients with depressive symptoms in which psychological treatment is integrated into low vision rehabilitation services. Low vision staff will be trained to deliver "problem solving therapy for primary care" (PST-PC), an effective psychological treatment developed specifically for delivery by non-mental health care staff. PST-PC is delivered in 8 weekly telephone sessions of 30-45 minutes duration and 4 monthly maintenance sessions. We predict this new integrated model of care will significantly reduce depressive symptoms and improve the quality of life for people with visual impairment.

Methods and Design:
A randomized controlled trial of PST-PC will be implemented nationally across low vision rehabilitation services provided by Vision Australia. Clients who screen positive for depressive symptoms and meet study criteria will be randomized to receive PST-PC or usual care, consisting of a referral to their general practitioner for more detailed assessment and treatment. Outcome measures include depressive symptoms and behaviors, quality of life, coping and psychological adjustment to visual impairment. Masked assessments will take place pre- and post-intervention as well as at 6- and 12-month follow-up.

Conclusion:
We anticipate that this innovative service delivery model will lead to sustained improvements in clients' quality of life in a cost effective manner and provide an innovative service delivery model suitable for other health care areas in which depression is co-morbid.

Progress on obesity prevention over 20 years in Australia and New Zealand

The lessons learned from over 20 years of obesity prevention efforts in Australia and New Zealand are presented. The obesity epidemic started in the 1980s but poor monitoring systems meant the rise in obesity prevalence initially went undetected. In the 1990s, experts started advocating for government action; however, it was the rapid increase in media reports on obesity in the early 2000s which created the pressure for action. Several, comprehensive reports produced some programme investment but no regulatory policies were implemented. The powerful food industry lobby ensured this lack of policies on front-of-pack food labelling, restrictions on unhealthy food marketing to children, or taxes on unhealthy foods. The New Zealand government even backpedalled by rescinding healthy school food guidelines and withdrawing funding for the comprehensive national obesity strategy. In 2007, Australian Governments started a major long term-investment in preventive health in order to improve economic productivity. Other positive initiatives, especially in Australia, were: the establishment of several advocacy organizations; successful, long-term, whole-of-community projects reducing childhood obesity; a national knowledge exchange system for practitioners; and some innovative programmes and social marketing. However, despite multiple reports and strong advocacy, key recommended regulatory policies remain unimplemented, largely due to the private sector interests dominating public policy development.

A new urban planning code's impact on walking: The residential environments project

Objectives. We examined whether people moving into a housing development designed according to a state government livable neighborhoods subdivision code engage in more walking than do people who move to other types of developments.

Methods. In a natural experiment of 1813 people building homes in 73 new housing developments in Perth, Western Australia, we surveyed participants before and then 12 and 36 months after moving. We measured self-reported walking using the Neighborhood Physical Activity Questionnaire and collected perceptions of the environment and self-selection factors. We calculated objective measures of the built environment using a Geographic Information System.

Results. After relocation, participants in livable versus conventional developments had greater street connectivity, residential density, land use mix, and access to destinations and more positive perceptions of their neighborhood (all P < .05). However, there were no significant differences in walking over time by type of development (P > .05).

Conclusions. Implementation of the Livable Neighborhoods Guidelines produced more supportive environments; however, the level of intervention was insufficient to encourage more walking. Evaluations of new urban planning policies need to incorporate longer term follow-up to allow time for new neighborhoods to develop.

Recyclable textiles functionalized with reduced graphene Oxide@ZnO for removal of oil spills and dye pollutants

A novel recyclable and flexible membrane was prepared for the removal of oil spills and organic dye pollutants, by functionalizing polyester textiles with reduced graphene oxide@ZnO nanocomposites using a layer-by-layer technique. The membrane showed efficient water/oil separation, and the amount of oil adsorbed by the membrane could be up to 23 times its own weight. The adsorption capacity was largely retained during many adsorption recycling cycles. The membrane also displayed highly efficient removal of a dye pollutant from water under simulated sunlight. The membrane maintained a near-original removal efficiency after five cycles of dye removal. This new type of membrane may find practical applications in the large-scale separation of organic pollutants from water, particularly in the field of oil spills clean-up and dye removal from industrial effluent.

Social moderation, assessment and assuring standards for accounting graduates

Evidencing student achievement of standards is a growing imperative worldwide. Key stakeholders (including current and prospective students, government, regulators and employers) want confidence that threshold learning standards in an accounting degree have been assured. Australia’s new higher education regulatory environment requires that student achievements are benchmarked against intended programme learning outcomes, guided by published disciplinary standards and a national qualifications framework, and against other higher education providers. Here, we report on a process involving academics from 10 universities, aided by professional practitioners, to establish and equip assessors to reliably assure threshold learning standards in accounting that are nationally comparable. Importantly, we are learning more about how standards are interpreted. Based on the premise that meaning is constructed from tacit experiences, social interactions and intentional reflection on explicit information, we report outcomes of three multi-part calibration interventions, situated around judgements of the quality of the written communication skills exhibited in student work and their related assessment tasks. Qualitative data from 30 participants in the calibration process suggest that they perceive that the process both assists them both in developing a shared understanding of the accounting threshold learning standards and in the redesign of assessment tasks to more validly assess the threshold learning standards.

Virtual worlds in Australian and New Zealand higher education: Remembering the past, understanding the present and imagining the future

3D virtual reality, including the current generation of multi-user virtual worlds, has had a long history of use in education and training, and it experienced a surge of renewed interest with the advent of Second Life in 2003. What followed shortly after were several years marked by considerable hype around the use of virtual worlds for teaching, learning and research in higher education. For the moment, uptake of the technology seems to have plateaued, with academics either maintaining the status quo and continuing to use virtual worlds as they have previously done or choosing to opt out altogether. This paper presents a brief review of the use of virtual worlds in the Australian and New Zealand higher education sector in the past and reports on its use in the sector at the present time, based on input from members of the Australian and New Zealand Virtual Worlds Working Group. It then adopts a forward-looking perspective amid the current climate of uncertainty, musing on future directions and offering suggestions for potential new applications in light of recent technological developments and innovations in the area.

Archaeobotany in Australia and New Guinea : Practice, potential and prospects

Archaeobotany is the study of plant remains from archaeological contexts. Despite Australasian research being at the forefront of several methodological innovations over the last three decades, archaeobotany is now a relatively peripheral concern to most archaeological projects in Australia and New Guinea. In this paper, many practicing archaeobotanists working in these regions argue for a more central role for archaeobotany in standard archaeological practice. An overview of archaeobotanical techniques and applications is presented, the potential for archaeobotany to address key historical research questions is indicated, and initiatives designed to promote archaeobotany and improve current practices are outlined.

Developing economies and the emergence of new stakeholder group: an examination of stakeholders in the Chinese stock market

As a consequence of the development of the Chinese economy, there has been an emergence of “new” stakeholder groups for the Chinese listed firms. New stakeholder groups include creditors, regulatory agencies, private investors, professional associations and environmentalists. With the use of secondary data, a review was undertaken to explore the emergence of these new stakeholder groups and discuss their influence over listed firms in China. The stakeholder typology developed by Mitchell et al (1997) is used to identify stakeholder attributes of each stakeholder group and assess their stakeholder power. The changes of stakeholder power over the years mirror China’s transition from a centrally planned economy to a more market oriented one.
